Only CAT E if we notify you. Only used in EXTEREME circumstances.
Yes, we do work nights, but there are 2 issues with that, No1, the price we charge goes up by quite a large factor (don't know how much) and No2, TERRAIN issues. We can only do nights if we can be certain that we'll be absolutely safe AT ALL TIMES during the procedures which really can't be altered for night tasks.
Weekends....Yes we do that, but I believe the price goes up!
Serial.......Archaic term, just read 'run' if you want to!
Quite nice replies from everyone though. We know we're not the easiest to work with and we know that after briefing you the plan nearly always changes but that's always down to the results that we obtain that sometimes require further runs to clarify the recordings.
